I IM ROVEMENT .lN GRAIN-BINDERS.

i Specificationformingpart of Letters Patent No. 197,182, dated November 13, 1877; application filed I r I November 8,1877.

Be it known that 1, WI LIAM A; Surrniu, of Washington city, District of Columbia, have invented a new and useful Improvement .in Grain-Binders, of which-the following is a specification: e y I The'object of my invention is tofurnish a machine that will bind the straw or stalks of N grain in bundles; and it consists in the devices and combinations of devices, as hereinafter set forth.

' ln fthe accompanying drawings, Figure lrepresents a V16w, l11 perspective, of myim proved binder n working position, the binding or wire-carryingarm being in an elevated position, ready to descend to encirclethe gavelwith thebinding-wire, and deliver said wire to the "twister. Fig.2 isa view, in elevation, of the. binder fi'om the stubble. side of the machine, with the table or grain receiver and 'supporting andjbinderframes in section to show the working. parts. Fig.3 is a plan view with the grain-receiver or binder-platform removed, and the reciprocating frame broken away, to show the operating mechanism. Fig.

- i represents a modification of the pivoted wirereceiving arm on dummy-gavel; Fig. 5, a section of the wire-spool I and its controlling devices, showing their construction and mode of 'operation;. and Fig. 6 sets forth a section of the wheel which operatesthe binding-arm and twister, and a modification of the pawls and ratchet which govern said wheel. 7 i

SI have shown my binder as applied to that class of harvesters which elevate the cut gram over the driving-wheel and deliver it in a suitable receptacle on the stubble side of the ma: chine; butit is equally applicable to machines of other construction.

The ordinary harvester-frame A is extended on the stubble side of the machine to form the necessary support for the binder. The bind ing mechanism is mounted upon and supported by the frame 13, tolwhich are attached suitable ways or slides B B which may be of any ordinary or preferred construction. The reciprocating carriage or frame 0, which supports and carries allithebinding mechanism,

moves in said ways, The carriage O is recip rocated by the chainD, which has imparted to it a continuous motion in one direction by the sprocket-wheels D D. The connection between thecarriage G and chain D is a wheel, E, (or may be an arm,) journaled at e' to said frame, and connected to the chain by a wristpin 0, journaled in an eye, 6 on] the chain,

' (thus the chain and wheel have a fixed relation to each other,) and the wheel E is provided with a ratchet or notch, j, which engages alternately with pawlsf' f pivoted to the carriage O, on opposite, sides thereof, and

serves to move said carriage in either direotion. As the carriage O is moving outward to deliver the bound bundle, the pawl f l comes in contact with the stop F, attached to the binder-frame, which releases said pawl fiom the notch f, and allows the wheel Eto turn on its journal and make one-half of a revolution,.when the ratchet will engage with the pawl on the opposite side of said carriage, and form a fixed relation between the driving-chain and carriage C, until the pawlis again released by the stop F on the opposite side of the binder-frame. The pawls f are held in position to engage with the ratchet or notch on the wheel E by the springs J. The pawl and notch may be constructed sov as to form a lock to the wheel E, as represented in Fig. 6.

The wrist-pin e on the wheel E is the same distance from the center of said wheel as the eye .on the chain is from the center of the sprocketwheels, so that the engagement of the driving parts is always complete, or has a fixedrelation, whether the carriage O is being reciprocated, or whethersaid carriage is standing, and the wheel E, with its pin 6, is being turned one-half of a revolution on its journal around either of the sprocket-wheels. The driving-chain moves the carriage alternately back and forth the distance from censaid frame or carriage to stop at each end of its reciprocation the length of time required for the chain to carry the wrist-pin one-half of a revolution of the sprocket-wheels.

To operate the binding or wire-carrying arm G, which is hinged or pivoted in the lugs or cars G G on the carriage G, I provide the wheel E with a cam-groove, g, which gives a reciprocating motion to the rack-bar Gr, through the medium of the pin or anti-friction roller g ,sec 1 red to said bar, and working in the cam-groove. The rack-bar is provided at its rear end with teeth or cogs g engaging with a segmental rack, g", on the end of the hinding-arm, near the pivot g on which the arm swings as it is raised and lowered to receive the gavel and apply the band thereto.

Any known or preferred twister may be used with this machine. I have, however, shown in the drawing the band twister and cutter invented by me, and patented November 6,1877, No. 196,949;

The band-twister H is operated by the Wheel 1 E, while the reciprocating carriage C is at rest, during the passage of the wrist-pin 6 around the sprocket-wheel from one side to the other. The twister H has a pinion, h, on its shank, which engages with the intermediate pinion h, which, in turn, engages with the segmental rack h on the wheel E. 7 To retain the twister in a fixed position during the disengagement of the pinion 7L2 and segmental rack h, the wheel E is provided with a flange, h, which, as theteeth of the segment and pinion disengage, falls into a corresponding recess in the flange h on the pinion h thus lockin g the twister, and preventing any rotation thereof until the rack is again brought in contact with the pinion.

The twister is journaled in the carriage C and bracket H fixed to said carriage. To give the necessary movement to the twister and cutter, as described in my aforesaid patent, I provide the pinion k with a cam-groove, h, in which the anti-friction roller on the bar H travels, giving said bar a short down-and-up movement at the end to which it is attached to the twister at each revolution of the pinion h. The pinion h may be dispensed with, and the twister and cutter operated directly from the wheel E. Thus the semi-rotation of the wheel E operates the arm G to carry the band to the twister, and the twister and cutter to twist and sever the hand.

To the grain-receiver or binder-platform I, I attach a spring-arm or dummy-gavel, J, in such position that as the carriage 0 moves up to receive a gavel the twister will be under or slightly back of said arm, and thus protected from the grain during the twisting of the band, and the band which is carried with the twister and binding-arm or needle will be on the outside of the gavel and said spring-arm, and as the binding-arm descends to encircle the gavel with the band the spring-arm will also be gathered and bound with the grain, and as the carriage moves back to deliver the bundlethe pivoted arm, which is retained in working position by the spring j, will be moved to one side of the path of the binder-arm and drawn out of the bundle, and resume its former or normal position. Should the binder be in operation, and no grain delivered thereto, the pivoted spring-arm or dummy-gavel will receive the band and hold the same during the process of securing together the ends thereof, and insure the regular operation of the mathe twister.

for the passage of the needle-arm asit delivers the bound bundle. The grain-board I extends.

chine, without knotting or. breaking the wire by pivoting it to the binder-carriage, and giving it a partial rotation bythe reciprocation of the carriage.

The arms of the dummy-gavel may be made of solid pieces of metal, or they may be composed of light spring-pieces, as represented at J, which will allow them to yield as the hand is twisted around it.

The binder-platform I is provided with a back or upright portion, 1 against which the gavel is compressed, and behind which the binding-arm descends to carry the band to Said back and] table are slotted over the back I, and ishing'ed at t to allow of the removal or adjustment of the bindertable. The needle K is provided with a ortion, K extending above thefarm G, to orm a cut-ofi to the flowing grail} 0n the board I?" while the bundle is being bound.

To compress the gavel plfeparatory to bindin g, I apply a sprin g-compressor, L, to the heel of the binding-arm, nearits' pivot-pin g andefx tend it as far forward as the band-carrying needle, and so shape and locate it that as the binder-arm descends to deliverthe band to; the twister the compressor willlcompress the.

gavel, whether large or small, [according to the power .of the spring.

The compressor may be made entirely separate from the binding-arm, andlhave motion imparted to it similar to that Of the bindingarm.

To the spring-compressor Iaffix. a fork or prongs, L L, which, as the binding-arm descends, are forced into the buiidle, and hold it in a fixed relation to the binderarm and carriage, and not allowed to twistas it is carried back to be delivered."

The band-spool M is supported in brackets or journal-bearings M" ll/l2, attached to the rear end of the carriage 111 the bracket M is journaled a ratchet-wheehm, having a square central opening to receive the pin m, which is made square at one end, and the band-spool is also provided with a square opening at one end, so as pin m, is inserted into the opening inj the" ratchet-wheel, spool, and bracket, the spool and ratchet-wheel will be locked to turn together, and the rotation of the spool will be on the journal of the ratchet-wheel, and the end of the pin in the bracket M.

The bracket M is extended a sufficient height to form a support for the pivoted band-guide M the lower end of which is formed into a pawl, M The guide and pawl swing on the pin m The pawl M is held in contact with the end of the pawl.

may. be varied by adjusting the screw m which has a bearingin the bracketM Thus the tensionof the band, as it is applied to the gavel to compress and bind the same, may be is sufficient to overcome the tension of the spring on the pawl. The spool is positively locked or prevented from turning, so that no wire will be let off, until the strain on the wire becomes greater than the predetermined compression to be given to the bundle, when the pawl will be disengaged from the ratchet-wheel,

and the spool left free to give 011' the band' without any tension, until the slack in the band allows the pawl to engagewiththe ratchetwheel.

By this construction the letting oil of the band is positively controlled, without regard to the weight of the spool, or whether it is filled or almost empty.

The binder-frame B is adjustable on the main frame by swinging horizontally on a ,tubular pivot, N, which is secured to the main frame A, and said tubular pivo,t forms the journalbearing for the shaft D of the sprocket-wheel The shaft 1) has secured to its lower end 'a bevel-gear wheel, D Engaging with said wheel is .a bevel-pinion, D, on the shaft D which has bearings on the main frame.

Motion is communicated to the sprocketwheel D from any convenient driving part of the machine, and through it to the pinion D and shaft D The operating parts of the binder all derive their moving-power from the shaft D and sprocket-wheel D, as hereinbefore described.

With this construction the relation of the driving-power and the binding mechanism always remains the same, whatever may be the adjustment of the binder-frame.

For convenience in adjusting the binder to the length of the grain, I place a hand-lever, 0, having the necessary detent-latch, in convenient reach of the driver, whose seat is located on the seat-frame P. To the lever O is connected a link extending to the bell-crank lever 0, which, in turn, is connected. to the binder-frame, so that the attendant, atwill,

while the machine is in motion, may make the necessary adjustment of the binder.

It is evident that this binding mechanism is applicable to tables having a straight sliding adjustment.
